Restoring Bridge Defaults 3-31
NB-30 Bridging
To halt a test in progress and return to the Bridge Status window, click on Cancel.
The results of the test will be displayed in the status Þeld next to the test button:
¥ Not in Loopback Ñ Indicates that the DSX-1 port is currently in normal
operating condition; a loopback test is not being performed.
¥ Loopback in Progress Ñ The DSX-1 port is undergoing a test.
¥ Network Loopback Ñ The remote port is currently looped toward the T1 link.
¥ Loopback Passed Ñ The test was successful, and the T1 link is valid.
¥ Loopback Failed Ñ The test failed, and the T1 link may be malfunctioning.
Viewing the T1 Link Channel Status
The DSX-1 Summary window also lets you see the status of each channel of the T1
link. Note that both bridges linked via the T1 line must share the same channel
assignment. Up to 24 channels can be used in an NB-30 T1 link.
An Enabled status indicates that the associated channel is assigned to the T1 link;
a Disabled status indicates the associated channel is not used for the link. The
administrative state of each channel is set via local management. Refer to your
NB-30 Local Management documentation for more information.
Restoring Bridge Defaults
From the Bridge Status window, you can use the Restore Defaults option to reset
bridge identifying and operating parameters back to their Þrmware default
settings.
The following operating parameters are accessible via SPECTRUM Element
Manager. The restored defaults will be visible on-screen.
¥ Bridge Location to LOCAL
¥ Ethernet Port Name (1) to ETHERNET PORT 1
¥ Remote Port Name (2) to REMOTE PORT
¥ Net 1 Name to LAN_1
¥ Net 2 Name to REMOTE LINK

CAUTION
Among the Þrmware defaults restored are those for Spanning Tree, Ethernet port
redundancy (accessible via local management and MIBTree), and T1 channel assignment
(accessible via local management and MIBTree). Make sure that network operations will
not be adversely affected before selecting the Restore Defaults option.
